Anyway, I suggest double-checking your page tables and MTRRs.

I asked Terry Lee to give this patchset a spin, and it seemed to work
well for our h/w use case. The size increase vs. OpenSSL 1.1.1n was
noticeable, but workable. We're good with merging it.

Are you sure you have the HttpDxe driver in your OVMF build? Looks like
you'd need to build with either -D NETWORK_HTTP_ENABLE or -D
NETWORK_HTTP_BOOT_ENABLE.
See https://github.com/tianocore/edk2/blob/master/OvmfPkg/README for
details on HTTPS.

tely, neither HobLib nor AllocatePages() has an interface for
setting the "Name" field. But you can call AllocatePages(), then search
the HOB list for the resulting HOB, and update it's AllocDescriptor.Name
field.

cal input. That helps avoid
unnecessary rebuilds of code which hasn't actually changed. It affects
items like the order of dependencies in the generated makefiles.
Setting PYTHONHASHSEED knocked several minutes off of the rebuild time
for one of our platforms. Recommended.

OK. Doesn't look like a big impact.

Sorry, gotta ask: does this make much difference in the size of the
compiled code? That's a constraint on many real-hardware X64 platforms,
especially for 32-bit code.

Yes, adding a new HOB type to represent free pool would probably be the easiest.
Or we could write or borrow a traditional malloc() implementation, similar to
DXE's pool allocator, and
would
avoid fragmenting the pool memory when non-pool HOBs are added. It
would probably be more code, though.

I'll add my agreement to Marvin and Jeff: a low-level sort routine like
this should let the caller be in charge of memory allocation, so it can
be used in the widest variety of contexts (SEC, exception handlers, APs,
etc.) So let's make the BufferOneElement parameter mandatory.

welcome this patch for that reason.
But I'd also like OVMF to benefit from this change even when it is built
with a traditional -- and regrettably, ever-growing -- DXE phase. I
welcome this patch for that reason too.
Thank you,

If those don't seem like worthwhile advantages, that's OK with me. I
